Valentine's Prismatic Orb

A spinning marble of light flashes from your hand and explodes at a point within range. Every creature within a 10ft. Radius Sphere must make a Constitution Saving Throw or be blinded for 1 minute. A blinded creature may repeat this save at the end of each of its turns, ending the effect on a success.

Every creature within a 20ft. Radius Sphere must also make a Dexterity Saving Throw or take 10d4 Piercing damage, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the Piercing damage increases by 2d4 for every slot level above 4th.
